0.9.0 - many improvements plus new functionality (plots, iosys, descfcn, optimal), deprecated np.matrix, py2.7

Version 0.9.0 of the Python Control Toolbox (python-control) contains a number of enhanced features and changes to functions. Some of these changes may require modifications to existing user code and, in addition, some default settings have changed that may affect the appearance of plots or operation of certain functions.

Significant new additions including improvements in the I/O systems modules that allow automatic interconnection of signals having the same name (via the interconnect function), generation and plotting of describing functions for closed loop systems with static nonlinearities, and a new optimal control module that allows basic computation of optimal controls (including model predictive controllers). Some of the changes that may break use code include the deprecation of the NumPy matrix type (2D NumPy arrays are used instead), changes in the return value for Nyquist plots (now returns number of encirclements rather than the frequency response), switching the default timebase of systems to be 0 rather than None (no timebase), and changes in the processing of return values for time and frequency responses (to make them more consistent). In many cases, the earlier behavior can be restored by calling use_legacy_defaults('0.8.4'). A full list of additions and changes is described below.

New features

Describing functions plots (#521 by murrayrm)

Implementation of initial_phase, wrap_phase keywords for bode_plot (#494 by murrayrm)
Added IPython LaTeX representation method for StateSpace objects (#450 by roryyorke)
New dynamics() and output() methods in StateSpace (#566 by sawyerbfuller)
FRD systems can now be created from a discrete time LTI system (#568 by bnavigator)
Cost and constraints are now allowed for flatsys.point_to_point() (#569 by murrayrm)

Interface changes
